Cob virtual currency

1.

According to the current difficulty calculation, we can dig about 1.012 Laite coins a day. This is the average calculation result in the mine pool. If there is an efficient mine pool or solo, maybe more

litecoin (abbreviated as LTC, currency symbol: 321;) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

design purpose

it is based on bitcoin protocol, but it is different from bitcoin in that even at the present stage, it can efficiently "mine" through consumer hardware. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin

transactions

a peer-to-peer network similar to bitcoin handles lightcoin transactions, balances, and issues through a script workload proof scheme (when a sufficiently small hash value is found, the, A block will be created, and the lightcoin will be issued. The process of discovering the hash value and creating the block is called "mining"). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable for "mining" with graphics processor (GPU). FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin

currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million

litecain is a free software project released under MIT / X11 license, which allows you to run, modify and the software according to your own needs. You can also release a modified version of the software if you like

the software is released in a completely transparent form, and users can independently verify the binary version and the corresponding source code

mine pool

the lightcoin is generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoins at one time. At present, the computing power of lightcoin is growing rapidly, and the miner can't find the mine through several computers. Therefore, it is necessary to join the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher

at present, the well-known mine pools include BTCC (original bitcoin China) mine pool, waltc.net fish pool (f2pool), wemineltc, coinotron, silverfish, liteguardian, litecoin pool.org, etc. But at present, the highest income is f2pool. Recently, it launched lightcoin theory income + 10% of mine pool subsidy = your actual income, which has attracted the attention of many miners and the instry

data block chain

litecoin block chain, compared with its competitor bitcoin, can handle larger transaction volume. Due to the more frequent generation of data blocks, the network can support more transactions without modifying the software in the future
as a result, businesses can obtain faster transaction confirmation, and they can still wait for more transaction confirmation when they sell large value procts

In fact, digital virtual currency is far from the above. Forbes magazine listed the top 30 virtual currencies in the market by their total market value and price as of 10:00 a.m. local time on the 27th. Caijing.com and venture capital Post said that there are at least 60 kinds of virtual currencies currently traded According to the Forbes report, bitcoin ranked first in market value and unit price. It was the lightcoin designed by Li Qiwei, a former Google programmer, that won "erlianya". In the past week up to the 27th, the price of lightcoin rose rapidly from $6 to $26, a considerable increase. The third to fifth place in the total market value are spot money, nominal money and prime money. The report counted the 24-hour gains as of the 27th. Almost all of the 30 currencies rose, with the biggest increase of the quark currency, reaching 278.55%. The report also said that almost all virtual currencies have taken a ride in the current round of bitcoin's rise, but most of them have poor business, with 8 companies with a total market value of less than $1 million and 19 companies with a unit price of less than $1

bitcoin is a new type of virtual currency, which is generated by a large number of calculations based on special algorithms. According to rigorous calculations, the stock of bitcoin is limited, with a total of 21 million, no more or less. After being created, bitcoin has rapidly become a "fixed asset" pursued by Internet speculators
in February 2014, mtgox, the world's largest trading platform, went bankrupt, casting a shadow on the whole bitcoin instry. Since the middle of 2014, the price of bitcoin has been in a downward trend for a long time
on August 12, 2015, the price of a bitcoin was only close to 1700 RMB
on the afternoon of February 8, 017, the inspection team of the business management department of the people's Bank of China interviewed the main principals of nine bitcoin trading platforms in Beijing, including "China bitcoin", "bitcoin trading network", "bitcoin", "yuncoin", "Yuanbao", "btc100", "jucoin", "coin shell" and "dahonghuo", which are engaged in bitcoin trading, Report the current problems of bitcoin trading platform, prompt the possible legal risk, policy risk and technical risk of the trading platform, understand the operation of the nine trading platforms, and put forward clear requirements: it is not allowed to engage in financial business such as financing currency, participate in money laundering activities, and violate the relevant national anti money laundering and anti money laundering regulations Foreign exchange management, payment and settlement and other financial laws and regulations shall not violate the state tax and instrial and commercial advertising management laws and regulations.

4. Virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher; The popular digital currencies in 2013 include bitcoin, Leyte coin, Fuyuan coin, doggy coin and so on
network virtual currency can be roughly divided into

the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.
